VENTILATED CREIVIATORY-CLOSET.

SPECIFICATION forming part of Letters Patent No. 446,340, dated February 10, 1891.

Application filed April 2, 1890. Serial No. 346,345, (No model.)

closet orr apparatus for burning refuse, ex-

cretory, or fecal matter.

'lhisinvention is animprovementin apparatus for receiving and destroying or burning excretory matters in dwelling-houses, audits object is to provide an odorless or gas-tight receptacle wherein the fecal matters can be collected and burned and the infectious noxious gases generated therefrom be destroyed or conducted off where their discharge cannot injuriously affectthe residents of the dwelling, and the escape of such gases therein be prevented. It is also designed to separate the solid and iiuid matters and conduct the latter out of the receptacle to a proper subterranean drain or outlet. These objects I accomplish by the apparatus illustrated in the drawing, and hereinafter described and claimed.

In the figure of the drawingis represented a furnace and receptacle combined, and preferably built up in sections.

A designates the lowermost section, preferably annular in transverse section, and mounted on feet or other proper supports, and forming the ash-pit, having a door a at one side.

B designates the fire-box section superimposed on section A and provided with an ordinary grate and a door b at one side.

C designates a third section of less diameter than section B, having a bottom c extending beyond the sides thereof sufficiently to rest upon the top edges of section B and sustain section C thereon. This section C forms the lower portion of the fecal-matter receptacle tion. Superimposed on section C may be other annular sections, two D D being illustrated in the drawing, according to the depth and size of fecal receptacle desired. The sections of the receptacle are or may be united by ange and bead joints, as illustrated, or

' ber through an openingfin part C,as shown,

and at top with a pipe G, leading to a chimney or flue. The casing has a door therein opposite door C in the receptacle.

H designates a pipe extending through sections A B into the bottom of section C. `Vlhis pipe, communicates at bottom with a drainpipe, by which iiuids will be conducted off, or it can be extended several fe'et into and below the ground and then packed with cement above its outlet to prevent rising of noxious vapors. Only uids are carried off through said pipe, and its upper end is provided with a sieve 71, to prevent solid matters entering therein.

eis an inwardly-projecting drain-flange on iop E, which conducts the water of condensation deposited from vapors rising in the receptacle to a point atone side thereof and delivers them into the mouth of a tube I, which extends downward into pipe II, as shown. The object is to separate luids from the solid matters in the receptacle.

J designates the soil-pipe communicating with the receptacle through an opening in one side of top E, as shown. The lower end thereof has an inner channel or bead j, the lowest point of which is directly above the mouth of tube I. In this channel the moisture Aand water descending the sides ofthe soil-pipe are caught and conducted into tube I, while solid matters descend into the receptacle. A bed of charcoal is kept in the receptacle, upon which the solid matters are de- ICO positcd. The soil-pipe is preferably set vertical, and at its upper cud is connected to a commode or privy seat.

K designates a veut-pipe leading from the upper section D into the draft-pipe G, and L is a gas-conducting pipe connected to pipe K outside the receptacle and extending down between the walls thereof and the casing into the fire-chamber, and adapted to conduct gases into or above the fire in said chamber. Pipe L may be disconnected` from pipe K when there is no fire in the chamber B, and pipe K be closed by a cap over the iiange by which pipe L is usually connected thereto, access being had for this purpose through an opening in casing F, closed by a door M. A shelf N is fixed in the casing near pipe G,on which a lamp can be placed when there is no i-re in the furnace for the purpose of creating an artificial draft in pipe G. The end of pipe K within pipe G has a bell-mouthk, and in front thereof is a conical delector O, secured Within the pipe. Vhen there is an upward draft through pipe G, this cone and bellmouth act as an ejector to draw gases from the fecal receptacle; but if there should be any back draft by accident through pipe G the cone defiects the draft out of pipe K into the space between the casing and receptacle, so that poisonous gases will not be driven back into the receptacle and thence into the soil-pipe or building. The matters deposited on the bed of charcoal 'accumulate until the receptacle is sufficiently charged to require cleaning. This can be ascertained by peepopenings, or known by the size of the apparatus, the number of persons using the same, and the length of time of its use. The urine and other fluids descending the soil-pipe are drained off into pipe II, and should any fall into the bed in the receptacle they will be leached by the charcoal, which absorbs poisonous gases. At proper intervals a fire is kindled in the fire-chamber and kept going until the charcoal and mattei' in the receptacle have been reduced to ashes. The charcoal materially' assists in facilitating the combustion of the matters. The resultant ashes can be removed and a fresh supply of charcoal introduced into the receptacle.

The apparatus can be used even while the fire is burning, as the gases are sucked out of the receptacle and the draft in pipe G creates a downward current through the soil-pipe if opened or uncovered. Preferably pipe G leads into the common house-flue. By using pipe L much of the gas evolved in the receptacle can be drawn into the fire-chamber and consumed.

Having thus described my invention, I

claiml. Ak furnace for burning refuse matters, comprising a fire-chamber section, a fecalmatter receptacle built up of cast-metal rings, and a cover closing the top thereof, the soilpipe entering` the receptacle through said cover, a tight easing inclosin g said receptacle and forming a cylindrical flue leading from the conibustion-chamber, the flue-pipe communicating with said casing, and the short pipe entering said flue-pipe and communieating with the fecal-matter receptacle, all substantially as set forth.

' 2. A furnace forburning fecal matters, consisting of a fire-chamber, a fecal-matter receptacle superimposed on the fire-chamber, but not communicating therewith, a soil-pipe entering the top of said receptacle, and a drain-pipe leading therefrom, in combination p with a metallic casing inclosing the fecalmatter receptacle and supported on the firechamberscction, the flue-pipe connected therewith, the pipe leading from said receptacle into the flue-pipe, and the drain-pipe and drip-pipe, all substantially as specified.

3. The combination of the fecal-matter receptacle having a conical top interiorly flanged to form a drain for Water of condensation, a drain-pipe for fluids only leading from said receptacle, the tube conducting Water of condensation from the top into said drain-pipe, and the soil-pipe connected with said receptacle, all substantially as set forth.

4. The combination of the fecal-matter receptacle having a conical top flanged on its inner side to form a drain, with the soil-pipe entering said top, having its lower end channeled, and the tube for conducting water from said drain andl channel into a drainpipe, substantially as specified.

5. The combination of the ash-pit and firechamber sections, the sections superimposed thereon, forming the fecal-matter receptacle, and the conical top closing said receptacle, having a flange on its under surface forming a drain for water of condensation, and the soil-pipe entering said top, and the fluiddraining tubes and pipes-with the casing inclosing said receptacle and communicating with the fire-chamber, adraft-pipe leading from said casing, and a vent-pipe leading from the receptacle into the draft-pipe, hav` ing a bell-mouth, and a conical deilector in the draft-tube, all constructed and arranged substantially as and for the purpose specified. In testimony that I claim the foregoing as my own I affix my signature in presen/ce of two witnesses.
